After some code change I have published my AJAXised web application to the server and the application failes to work properly - something weird is going on, as all .aspx pages are displayed as an ASPX markup text (page declaration, html controls, etc.), rather than a page is being rendered as an html. I have not changed the webconfig, only changed my pages' content/code behind.
View 4 RepliesI am hoping I am in the right place for this, I have a web application which has been running for about 4 years recently I updated my Ajax to the most recent version it continued to work OK then I changed from ScriptManager to ToolkitScriptManager now I get an error moving from my default page

View 2 RepliesFor our ASP.NET project for school we had to build a sport event management web application.
We provide the application in three languages (English, Dutch & French) which you can switch all the time. This has worked all the time for all users, well that's what we think anyway.
Yesterday I found out that switching from one to another language isn't working for 2 of our users. So I started testing a bit and I always got this error.
I'll try to explain what happens behind the doors when changing the language:
First of all the current language is saved in a session so we don't have to check the user row every time a page loads. Besides that we save the language in the users row in the database.
Users Table:
Id int
Unchecked
Email varchar(150)
Unchecked
When I try to Update or Delete a single selected item, it throws a "Row not found or changed." exception. Basically I only did a linq query and use most of the auto-generate function. I added LinqDataSource1_ContextCreated function,

AutoGenerateDeleteButton="True" AutoGenerateEditButton="True"

I do this:
public ActionResult Index([Bind(exclude="Name")]User user){} and my form in View does't include "Name" ,"Name" is null the problem comes....
when I use the MVC2 RC(Visual Studio 2010 RC),It works will the Model Verification didn't check the "Name" property there are no errrers in ModelState but in the MVC2 (Visual Studio 2010,I downloaded it two days ago,the newest version) I changed nothing! but it doesn't work!~ there is an error in the ModelState and tells :The "Name" is null =.=|||
well what i want to find out is how can i figure out if some change occurd in page when postback , i mean when the first state of the page hahe any changes after postback . I thought maybe somehow to compare viewstaes but i can not find out how can i do that.

Now i have a problem i cant figure out, i cant update data from a dropdown list, in the database using the updatemodel, that are foreign keys. Just all other data wich are not foreign keys and primary keys are updateable. These are automaticly created in the sql entity model.

View 3 RepliesSelectedIndex_Changed event occurs when selection changes, and selection is changed or not is decided by comparing dropdowns current selectedIndex and its value in viewstate.
When we changes dropdown's selected Item using Javascript, it does not change the viewstate's value (which is previously selectedIndex). Now if you change dropdown's selectedIndex to any new index it will work fine, but if you select the previously selectedIndex (which we reset using javascript), then postback will occur, but selectedIndex_changed function will not get fired because in viewstate of dropdown, selectedIndex is same as the Index we select after resetting it using javascript.
using asp.net you could create a listbox_valueChanged event and handle the user selection inside the event handler. How could i implement such a functionality using asp.net mvc? I guess that the best way could be to use ajax techniques in order to manage the user selection on the client side.

View 1 RepliesI have a Datagrid on ASP.NET web form which I have bound to a data source and set it to have 10 records per page. I also have a hyper link column on the Datagrid , such that a user can navigate to another page (details page) from the list. On the details page, they have "Cancle" button to return to the Datagrid pageI am looking for sample code snippet on the Server Side on how to specify the page index to set the Datagrid after data binding. The idea is to ensure the user navigates to the same page index they were on.
View 1 RepliesWhat is the best way to get the value of a dropdownlist control before it has been changed and after it has been changed. Can it be done in one routine? In other words, if a user clicks on a dropdownlist control and changes it's value, I need to get the old value and the new value and send both these values as input parameters to a stored proc.
View 3 RepliesI would like to perform a postback when the droplistlist selected value changes, but only if it was changed via expanding the downdown and clicking an option, not is the user tabs to the control and uses the arrow keys. The reason for this is simple, keyboard accessibility.

I have a page that shows the value of a property of my model. The value of that property is changed in the action-method of the controller (that recieves the model as a parameter). It turns out that this line of code:
<%= Html.TextBoxFor(m => m.Problem)%>
does not represent the value that it got in the action-method-code (just the value it got from the POST), but this does:
<input type="text" value="<%= string.IsNullOrEmpty(Model.Problem) ? "" : Html.Encode(Model.Problem) %>" />
Is this a bug or is some caching-mechanism working against me?
BTW, it is especially annoying when using HIDDENs, because the user can never change that value at all... That's how I found out...
I have a demo-project demonstrating the problem here for download. It is based on the default-application, so very small.
I have a rather short (~30 item) CheckboxList control and when it changes, I need to know which Checkbox changed.
I've got the CheckboxList set to AutoPostBack so I know only one Checkbox changed, but I don't know how to detect which one.
Unfortunately, the SelectedIndex property of the CheckboxList is useless. I'm sniffing around checking the ViewState, but I'm not sure if that'll work or how I go about that.
